Superstar chef — and this weekend’s cover boy — Jamie Oliver is on a mission to teach people how to become healthy eaters. Continuing the campaign he started in his native England, Oliver is now bringing his new book Jamie’s Food Revolution to the U.S. Associate editor. T.J. Walter caught up with the affable English chef when he was on his way to Huntington, W.Va. — 2009’s most unhealthy city in America — and the site of Oliver’s new, 6-week ABC primetime series airing this spring. Speaking bluntly about how Americans and Brits alike are in battle with obesity and overall bad health, Oliver says that, in most of the research he has done, America and England have many of the same problems and the solution is a simple one for most people: learn how to cook for yourself. In this week’s cover story, Oliver offers nine easy steps that can radically change the way you eat and save you money. Plus, you can pose a food challenge or question to Oliver, who is going to answer one reader’s query in an upcoming issue.
